According to an exemplary embodiment, the second wire D1 may include a plurality of connecting wires D1 c that are spaced apart from each other and are connected to each of the sub-pixels SP1 through SP3, a common wire D1 b that may be commonly connected to the plurality of connecting wires D1 c, and a body wire D1 a that may be connected to the common wire D1 b and formed to correspond to a side surface of one of the sub-pixels SP1 through SP3, for example, the sub-pixel SP1.

In the display apparatus 400 according to the current embodiment, the penetrating portion 410 may be formed in the substrate 401, and flexibility of the substrate 401 may be increased and the weight of the substrate 401 may be decreased.

The separation area BA may be formed between the pixels PU1 through PU3 from among areas of the substrate 401 such that the substrate 401 may be easily transformed, for example, bent, curved, or rolled, around the pixels PU1 through PU3 and stress generated during the transformation may be reduced or blocked. If the display apparatus 400 is applied as a bending display apparatus, a flexible display apparatus, or a stretchable display apparatus, the display apparatus 400 may have high flexibility and reduced abnormal transformation.

According to an exemplary embodiment, since the penetrating portion 410 may include the first penetrating portion 411 extending in one direction and the second penetrating portion 412 extending in a direction crossing the one direction, the flexibility of the substrate 401 may be obtained even when the substrate 401 is bent, curved, or rolled in any direction, abnormal transformation of the substrate 401 may be prevented, and durability of the substrate 401 may be improved. Accordingly, convenience of a user may be improved when the display apparatus 400 is used, for example, the display apparatus 400 may be applied to a wearable apparatus.

According to an exemplary embodiment, the second penetrating portion 412 may be disposed between two adjacent first penetrating portions 411 from among the plurality of first penetrating portions 411, and a crack may be prevented from being generated in a length direction of the first penetrating portion 411 of the substrate 401 by extending the first penetrating portion 411 in one direction.

The first penetrating portion 411 may be disposed between two adjacent second penetrating portions 412 from among the plurality of second penetrating portions 412, and a crack may be prevented from being generated in a length direction of the second penetrating portion 412 of the substrate 401 by extending the second penetrating portion 412 in one direction.

The pixels PU1 through PU3 may each include the plurality of sub-pixels SP1 through SP3 that are arranged in one direction, wherein a direction the sub-pixels SP1 through SP3 of the pixel PU1 are arranged and a direction the sub-pixels SP1 through SP3 adjacent to the sub-pixels SP1 through SP3 of the pixel PU1 cross each other. Accordingly, the sub-pixels SP1 through SP3 may be arranged to correspond to arrangement directions of the first and second penetrating portions 411 and 412, and even if the arrangement directions of the first and second penetrating portions 411 and 412 are different from each other, visual unevenness with respect to the pixels PU1 through PU3 may be reduced, and an image quality characteristic of the display apparatus 400 may be improved.

The display apparatus 400 according to the current embodiment may include the at least one wire, i.e., the first wires SL1 through SL3, the second wires V1 through V3, and the third wires D1 through D3, wherein the first wires SL1 through SL3, the second wires V1 through V3, and the third wires D1 through D3 do not overlap but are spaced apart from the penetrating portion 410. Accordingly, the penetrating portion 410 may improve the flexibility and durability of the substrate 401 0. The first wires SL1 through SL3, the second wires V1 through V3, and the third wires D1 through D3 may be prevented from being detached from the penetrating portion 410 since they do not overlap the penetrating portion 410, and may be prevented from being contaminated by a gas, such as external oxygen, or degenerated by moisture.

The first wires SL1 through SL3 from among the at least one wire may extend in one direction, may have a bent area, and may be periodically repeated, and unevenness of the display device 400 caused by the first wires SL1 and SL3 may be reduced or prevented. The second wires V1 through V3 and the third wires D1 through D3 may reduce or prevent the unevenness.

The second wires V1 through V3 and the third wires D1 through D3, which may extend in the same direction may be formed not to overlap each other, and interference therebetween may be reduced. By forming the bent areas of the second wires V1 through V3 and the third wires D1 through D3 to correspond to different second penetrating portions 412, reduction of an electric characteristic of the display apparatus 400 caused by interference at the bent areas of the second wires V1 through V3 and the third wires D1 through D3 may be prevented.

Each of the pixels PU1 through PU3 may include the sub-pixels SP1 through SP3 arranged in a certain direction, and each of the at least one wire may be connected to the sub-pixels SP1 through SP3 and may be curved to be spaced apart from the penetrating portion 410, and the at least one wire may include a plurality of connecting wires, a common wire, and a body wire connected to the sub-pixels SP1 through SP3. Accordingly, the first wires SL1 through SL3, the second wires V1 through V3, and the third wires D1 through D3 may be electrically connected to the sub-pixels SP1 through SP3 without overlapping the penetrating portion 410.

By way of summation and review, display apparatuses may be replaced by portable flat panel type display apparatuses.

It may be not easy to improve durability of portable flat panel type display apparatuses due to difficulties in manufacturing processes, for example, difficulties in manufacturing the portable flat panel type display apparatuses to have a certain thickness. For example, portable flat panel type display apparatuses may need to be flexible according to an intention of a user or during manufacture, for example, may need to be bent or folded. However, it may not be easy to manufacture durable portable flat panel type display apparatuses while obtaining flexibility.

As described above, according to one or more exemplary embodiments, a display apparatus may improve convenience of a user.
